Basically, are third party submissions (35 U.S.C. 122(e)) a proper subset of protests (37 CFR 1.291) in terms of what evidence and arguments can be presented?
I have the opportunity to file a protest on an unpublished continuation application. Although I don't know the claims, I plan to make general arguments against patentability (103, 112, IC) based on claims of the issued parent application. After doing so, I assume there is no benefit to filing a third party submission?
